Tape backup has traditionally been the mainstay of enterprise data protection when long-term data protection is required. As disk technologies have improved and economies of scale have driven down prices, disk adoption rates have surged and it would appear disk is poised to eclipse tape as the dominant backup platform and relegate tape to a minor archival and disaster recovery role.

An ad hoc wireless network supports data networking without an infrastructure, so that users can use network services while continually moving. Each move of the mobile host affects the topology of the network and the transmission route. The Ad Hoc Backup Node Setup Routing Protocol (ABRP) is proposed to focus attention on the intrinsic properties of the ad hoc wireless networks. Basically, ABRP...

Automated lip reading from videos requires segmentation. Threshold-based segmentation is straightforward, but it rarely used. This study proposes a histogram threshold based on the feedback of shape information. Both good and bad examples were used to train an $$\epsilon $$ -support vector regression model infer accuracy region shape. The was optimised minimise error. proposed method tested 895...
